a new Marine Animat <?(j. 
the whole is in motion, produces a plead ng effe<d, and is mod: 
driking when the fun is very bright. The membranes, how- 
ever, at fome particular times appear to be of the fame colour. 
While the membranes are in motion, a little mucus is often 
fepa rated from the tentacula at the point of the cone. Upon 
the lead motion being given to the water, the con^s are imme- 
diately, and very fuddenly, drawn in. 
This apparatus for catching food is the mod delicate and 
complicated that I have feen ; but I fhall not trouble you with 
any conje&ures upon what that food may be, as I have not 
attained diffident knowledge of the animal to fpeak with the 
dualled certainty. 
I have endeavoured' to defcribe the external’ appearances as I 
faw them ; and have annexed two drawings of the animal 
in its two different dates, one in fearch of food; and one while 
lying at red ; thefe are a > little magnified, to fhow the parts 
more didin dly. 
I fhall not fay any thing of the internal parts, or their ufes, 
as the animal is in your poffeffion, who are fo much better able 
to explain its internal (economy.
